Solar System Exploration Program
The Planetary Missions Program Office is a division of NASA headquartered at the Marshall Space Flight Center, formed by the agency's Science Mission Directorate (SMD). Succeeding the Discovery and New Frontiers Program Office, it was established in 2014 to manage the Discovery and New Frontiers programs of low and medium-cost missions by third-party institutions, and the Solar System Exploration program of NASA-led missions that focus on prioritized planetary science objectives. The Discovery and New Frontiers programs were established in 1992 and 2001 respectively, and have launched fourteen primary missions together, along with two missions launched under the administration of the Planetary Missions Program Office. The Solar System Exploration Program was established alongside the office, with three missions planned for launch under the new program. History The Planetary Missions Program Office was established in late 2014 as part of a series of changes implemented by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Double Asteroid Redirection Test
Double Asteroid Redirection Test (DART) is a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. The asteroid selected for the test poses no actual threat to Earth and was selected for the convenience of the test. The probe was launched from Earth on 24 November 2021, and on 26 September 2022 intentionally crashed into Dimorphos, the minor-planet moon of the asteroid Didymos. On 11 October, NASA declared DART a success, confirming it had shortened Dimorphos' orbital period around Didymos by about 32 minutes, surpassing the pre-defined success threshold of 73 seconds. DART is a joint project between NASA and the Johns Hopkins Applied Physics Laboratory (APL). The project was funded through NASA's Planetary Defense Coordination Office, managed by NASA's Planetary Missions Program Office a ...

Explorer Program
The Explorers program is a NASA exploration program that provides flight opportunities for physics, geophysics, heliophysics, and astrophysics investigations from space. Launched in 1958, Explorer 1 was the first spacecraft of the United States to achieve orbit. Over 90 space missions have been launched since. Starting with Explorer 6, it has been operated by NASA, with regular collaboration with a variety of other institutions, including many international partners. Launchers for the Explorer program have included Juno I, Juno II, various Thor, Scout, Delta and Pegasus launch vehicles, and Falcon 9. The program has three classes: Medium-Class Explorers (MIDEX), Small Explorers (SMEX), and University-Class Explorers (UNEX), with select Missions of Opportunity operated with other agencies. History Early Explorer satellites The Explorer program began as a U.S. Army proposal (Project Orbiter) to place a "civilian" artificial satellite into orbit during the International ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System.

Space Station Freedom
Space Station ''Freedom'' was a NASA project to construct a permanently crewed Earth-orbiting space station in the 1980s. Although approved by then-president Ronald Reagan and announced in the 1984 State of the Union address, ''Freedom'' was never constructed or completed as originally designed, and after several cutbacks, the project evolved into the International Space Station program. Space Station ''Freedom'' was a multinational collaborative project involving four participating space agencies: NASA (United States), NASDA ( Japan), ESA (Europe), and CSA (Canada). Original proposal As the Apollo program began to wind down in the late 1960s, there were numerous proposals for what should follow it. Of the many proposals, large and small, three major themes emerged. Foremost among them was a crewed mission to Mars, using systems not unlike the ones used for Apollo. A permanent space station was also a major goal, both to help construct the large spacecraft needed for a Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presidency Of George H
A presidency is an administration or the executive, the collective administrative and governmental entity that exists around an office of president of a state or nation. Although often the executive branch of government, and often personified by a single elected person who holds the office of "president", in practice, the presidency includes a much larger collective of people, such as chiefs of staff, advisers and other bureaucrats. Although often led by a single person, presidencies can also be of a collective nature, such as the presidency of the European Union is held on a rotating basis by the various national governments of the member states. Alternatively, the term presidency can also be applied to the governing authority of some churches, and may even refer to the holder of a non-governmental office of president in a corporation, business, charity, university, etc. or the institutional arrangement around them. For example, "the presidency of the Red Cross refused to support h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Exploration Initiative
The Space Exploration Initiative was a 1989–1993 space public policy initiative of the George H. W. Bush administration. On July 20, 1989, the 20th anniversary of the Apollo 11 Moon landing, US President George H. W. Bush announced plans for what came to be known as the Space Exploration Initiative (SEI). In a speech on the steps of the National Air and Space Museum he described plans calling for constructing Space Station Freedom, sending humans back to the Moon "to stay" and ultimately sending astronauts to explore Mars. He proposed not a 10-year Apollo-style plan, but a long-range continuing commitment based on the three above elements, ending with "a journey into tomorrow – a journey to another planet – a manned mission to Mars." The President noted it was humanity's destiny to explore, and America's destiny to lead. He asked Vice President Dan Quayle to lead the National Space Council in determining what was needed to carry out these missions in terms of money, manpo ...

Planetary Observer Program
The Planetary Observer program is a cancelled space exploration program designed by NASA to provide cheaper planetary orbiters by using Earth-orbiting satellite components and technology, using solar panels for power, and a common spacecraft bus platform for all Planetary Observer-class probes. Only one spacecraft of this class was eventually constructed—the ''Mars Observer''. History After the flagship multibillion-dollar missions of the 1970s, in the 1980s NASA was looking for a new, more affordable direction for the 1990s and beyond. Two projects were conceived by NASA's Solar System Exploration Committee in 1983, the Planetary Observer program and ''Mariner Mark II''. The Observer program, starting with ''Mars Observer'', was envisioned as a series of low-cost missions to the inner Solar System, based on commercial Earth satellites. The Mariner Mark II, on the other hand, was to be a series of large spacecraft for the exploration of the outer Solar System. The first Planet ...
